2017-2019 Silverado & Sierra 2500 & 3500 6.6L Duramax L5P PPE Allison Thermal Bypass Valve Features:

  • Feed 100% of the transmission fluid through the front-mounted transmission coolers
  • Neodymium magnet equipped service plug removes metal particles
  • Increased flow compared to the factory-restrictive thermostat even when itÂ’s fully opened
  • Billet aluminum construction
  • Easy bolt-on installation
Add another measure of protection and increase fluid flow with the easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for the GM L5P Duramax Diesel.

The OEM part has restrictive internal passages. When the OEM valve fails in the closed position, transmission fluid doesnÂ’t reach your cooler. This can be caused by mechanical failure or debris. The result of stock valve failure can cause the transmission to dangerously overheat. Without properly cooled transmission fluid, the demands of towing and rigorous stop-and-go driving conditions shorten the life of transmission components. The PPE Bypass Valve eliminates the mechanical valve which maximizes fluid flow from the transmission cooler.

For further protection, a Neodymium magnet equipped service plug has been added. The removable plug traps ferrous debris and can be accessed to remove particles from the system. The factory part does not have this feature.
